This veggie-packed alternative to the classic tuna bake dish will instantly become a crowd favourite. Although this recipe is super low-calorie and stocked full of better ingredients, it definitely doesn’t lose any of that classically creamy, cheesy flavour that has made the original so popular. It’s a great dish for whipping up on nights when you’re looking for something healthy yet still fairly straightforward to bake or when you’re serving up to a hungry crowd. It’s best served on its own however, you can also pop a simple garden salad with cherry tomatoes on the plate if you’re looking to really complement the flavours. Enjoy!
